WILLIAM M. MGKENZIE, OF DORCI-IESTER CENTER, MASSACHUSETTS.

SEPARATOR.

Application filed March 29, 1913.

To zZZ whom it may concern:

Be it known that I, WILLIAM M. MCKEN- zin, a citizen of the UnitedStates, residing at Dorchester Center, in the county of Suffolk andState of Massachusetts, have invented certain new and usefulImprovements in Separators, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to separators especially adapted to be used forseparating screw machine products from chips after the oil has beenextracted therefrom; the object being to provide a separator which is soconstructed that the finished products can be quickly separated from theshavings without handling the same, thereby overcoming the difiicultiesnow existing in separating the products from screw machines.

Another object of the invention is to provide a separator in which anair blast is employed for separating the shavings from the articlesproduced on the screw machine wherein the shavings and articles areplaced in a receiving box from which they are forced onto a shaker fordistributing the same, which is provided with a reticulated lower endallowing` the air blast to act partly upon the shavings and articlesbefore they are discharged therefrom, whereby the lighter articles willbe blown from off of the reticulated shaker and out of the falling massof articles into another portion of the separator from which they aredischarged into a suitable receptacle; the finished articles or productsbeing discharged at another point from the separator.

Another object of the invention is to provide a separator which isprovided with means for regulating the air blast in accord ance to thenature of the products being separated; the separator having a sightopening through which the operator can watch the separating action ofthe air blast upon the products and thereby regulate the same in orderto prevent too heavy a blast which would cause the finished products tobe blown with the shavings into the receiving compartment.

Another and further object of the invention, is to provide the separatorwith `a finished product-receiving trough having a bot- A tom formed ofwood or other soft material in order to prevent the finished productsfrom being injured by the impact therewith in falling from the shaker.

Specification of Letters Patent.

Patented Jan., 26, 1915.. serial No. 757,636.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

ln the drawings-Figure.1, is a side elevation of my improved separatorpartly broken away, showing the interior construction of the shaker andproduct-receiving trough; and Fig. 2, is a top plan of the separator.

Like numerals of reference refer to like parts in the several figures ofthe drawings.

1n the drawing, 1 indicates a suitable base upon one end of which ismounted a casing 2 having an extended portion 3 forming a compartmentfor receiving the shavings and like articles of the material placed inthe separator, as will be later described. rlhe extension 3 is providedwith a reticuiated end 4f and top portion 5 forming an exnaust for theair and the lower end of said extension forms a receptacle which isprovided with a suitable discharge opening, not shown, through which theshavings are adapted to pass and be caught by a suitable receptacle, notshown.

The casing 2 is provided with a productreceiving trough 6 having awooden bottom 7 inclined as shown. said trough being an extension of anair blast Hue 8 and separated therefrom by a reticulated partition 9. asclearly shown, for preventing the finished products from passing intothe same over the outlet 10 which is provided with a discharge opening11 through which the finished products are adapted to be discharged.

Extending into the casing 2 above the flue 8 is a shaker 12 providedwith a closed top portion 13 and a reticulated lower end 14 whichextends over the receiving trough 6; said shaker being provided withtransverse rods 15 mounted upon grooved rollers 16 in order to allow thesame to be reciprocated easily in order to distribute the products andshavings over the bottom of the shaker so that when they are dischargedfrom the lower end the air blast will be allowed to have full force uponthe same, as will be later described.

The base l is provided with standards 17 at its opposite end supportinga receiving box 18 having a discharge chute 19 extending into the shaker12. as clearly shown in F ig. 1, through which the shavings and productsare adapted to be forced manually but of course, it is understood thatvarious forms of receiving and distributing receptacles could beemployed for mechanically discharging the contents into the shaker.

Mounted on the base l between the uprights 17 is a blower 2O providedwith a discharge 21 connected to the flue S by a coupling 22 which isprovided with a reciproeating valve 23 to which is connected anoperating rod 24; the upper end of which has a pivotal connection withan arm 25 fixed on a shaft 26 mounted in suitable depending bracketsdepending from the boX 18. lThe shaft 26 at one end, is provided with alever 27 having a hand lever 2S carrying a pin 29 adapted to co-act witha number of openings L 30 of a plate 31 fixed on the side of the box 1Sby means of which the lever 27 can be locked in its adjusted position,whereby the adjusted position of the valve can be maintained. It will beseen by this construction, that the air blast can be regulated byoperating the valve through the mechanism hereinbefore fully set forthso as to adjust the air pressure according to the kind of products beingseparated.

The blower 20 is provided with a fan shaft 33 having a drive pulley 34at one end, which can be driven by a belt extending from a power shaft,not shown, or the same can be driven directly from a motor. However, themanner of driving this shaft forms no part of my invention.

Mounted in suitable bearings, not shown, is a drive shaft which isdriven by a twisted belt 36 passing over a pulley 37 carried by theshaft 33 and a pulley 88 carried by the shaft 35, the pulley 37 having asmaller diameter than the pulley 38 in order to reduce the speed of theshaft 35. -The shaft 35 is provided with a pulley 39 carrying a belt 40which extends transversely and passes over a pulley 41 carried by acounter shaft 42 mounted in suitable bearings 43 and 44 carriedrespectively by the casing 2 and standard 17. The end of the shaft 42 isprovided with a crank 45 carrying a wrist-.

pin 4G on which 1s mounted a pitman-rod 47; the free end of which ispivotally connected to a depending bracket 48 carried by the shaker 12.From the above, it will be seen that through the medium of thecounter-shaft and driving connections, the speed of the drive shaft isreduced in order to prevent the shaker from being operated at an excessrate of speed.

The casing 2 is provided with a sight opening 49 in a hinged door 50above the shaker, and the casing is provided with a light-receivingbasket 51 in which an incandescent lamp is adapted to be placed in orderto illuminate the inside of the casing so that the operator can inspectthe separation so as to adjust the valve to regulate the air blastaccording to the material being.

separated.

The operation of carrying out the separation with a machine as setforth, is as follows: The products and shavings are placed in the boxand the operator forces the same into the shaker, it of course beingunderstood that the fan of the blower is being driven and that theshaker is being reciprocated simultaneously through the medium of thebelts and pulleys and as the products are deposited upon the shaker bythe reciprocation thereof, they are distributed and by the inclinationof the shaker gradually work to the lo'wer end upon the reticulatedportion, at which point they are subjected to the air blast which blowsthe lighter particles or shavings into the receiving chamber; theparticles failing to be lifted by the air blast, are then dischargedfrom the shaker where they are subjected to the full blast of air andall of the lighter particles which have not previously been removed areblown to the upper portion of the casing and drop into theshaving-receiving compartment. The heavy particles of value, such as thefinished products, drop into the inclined trough 6 upon the cushionedbottom 7 and by gravity, are discharged through the outlet 10 anddischarge opening 11 into the suitable receptacles. As the separation isbeing carried out, the operator can watch the same through the sightopening 49 and regulate the air blast by adjusting the valve.
